The review of Story Server is quite outdated... The product now offers extensive content managment, personalization and cache management. Yes, cache management is important... if you perform a database operation for every page generation then you still need to get that information from the database, process it, format it in HTML, then deliver it to the client. With Vignette's patented cache management, the generated HTML is cached, and hence delivered without the processing overhead. This is part of what the industry calls scalability.
